Material losses in compound fertilizer production
Thread Content
When formulating compounds for fertilizer production, nitrogen nutrients tend to be lost easily, especially in ammonium carbonate and ammonium chloride. Therefore, the amount of nutrients included in the formula should not be too high, in order to prevent the resulting products from having an excessive nutrient content and thus avoiding unnecessary losses. However, the loss rates vary depending on the formula used; generally, urine-based formulas have lower loss rates, while chlorine-based formulas have higher loss rates, which results in greater increases in costs. I would like to ask the experts here: what are the typical loss rates? What are the differences in loss rates among various raw materials? What is the main component of the dust present in the drying exhaust gases? Let’s exchange ideas on this
I would also like to learn about this aspect, especially the loss rate of ammonium carbonate (including the loss rate of nitrogen in it and the overall loss rate)
Different companies have different operating methods, resulting in varying levels of loss; likewise, the condition of each device also affects the level of loss.
In the production of compound fertilizers, if production management is proper, the loss of its main raw materials should be able to be kept within 3%, right? I ask the experts to discuss this issue as quantitatively as possible.
Reply to 3# yfyf001: Although it can be said that way, there must still be a range. I hope there’s a quantitative figure.
I have calculated the losses in several production lines; the key factors are the efficiency of the drying and exhaust systems as well as the production formula. If urea is used, the losses are very low, while with an ammonium chloride formula the losses are around 4%, roughly half of that amount. I’m referring to granulation using cylinders here. Disk granulation incurs no losses; the density even increases by half
May I ask expert zuo923: Have you overestimated the material loss for high-altitude compound fertilizers? Is its loss high?
This can be done by comparing the manufacturer’s own production formula with the actual output, as well as the nutrients measured through quality control tests. Since the equipment used in each production line varies, the consumption levels will also differ. The 3% figure mentioned earlier can be considered a fairly good level of control; some companies, however, exceed this range
Expert on staying drunk: What is the typical level of material loss in the production process of high-nutrient compound fertilizers that you are familiar with? What percentage approximately?

Friend Wangziyouqin: What manufacturing process is used for your low-nitrogen compound fertilizers?
